Copper is perhaps one of the most important materials on earth because it is used for electricity and computers. It is also one of the main businesses from the world's largest economies, including the United States and Canada. Countries for example Chile, Zaire, Zambia, and Poland also produce significant amounts of copper.
Characteristics of copper
Copper is used in a lot of industries, because it's very ductile. It is the perfect metal in making wires, because not only will it be cold-rolled down to one one-thousandth inch thick - its could be lengthened as much as 5,000 times through a process called cold drawing.
Copper's unmatched utility is a result of its ability to form alloys readily with just about all metals. But apart from being functional, copper can be rather 'attractive' - it provides a nice color and luster and needs a high polish.
Important Purposes of Copper
Copper is mostly used in electrical equipment. Virtually all electrical devices run on copper wiring because copper is affordable and highly conductive, with many different free electrons that can transmit the current efficiently.
Copper can also be very important in fashioning metal items like pipes, tubings, plumbing fixtures, hardware and machine tools. It really is literally a part of everyday routine. It is even used for cooking utensils, although it is usually coated with tin, so that it does not form harmful compounds with food properties. Copper also finds its way into the transportation industry, refrigeration equipment, and other miscellaneous uses. Obviously you know that the penny on your bottom line is made of copper too.
Copper and computers
Computers rely on copper used to build integrated circuits and chips, among many other parts. It is quickly replacing aluminum because the main chip material. Research has found that copper won't make computers cheaper, but also help them make faster calculations.
